Unit 40: Computer Aided Manufacturing and
Planning
Level: 3
Unit type: Internal
Guided learning hours: 60
Unit in brief
Learners examine manufacturing-process automation and planning using computer software and
technology. Learners will simulate the manufacture of a component.
Unit introduction
Computer-aided manufacturing (CAM) is used extensively to manufacture products efficiently
and effectively by world-class-manufacturing organisations. CAM involves the control by software
of machine tools and associated systems to produce components. These systems are used to
automate and plan the manufacture of products and components, such as cars, computers and
medical devices, efficiently and effectively.
In this unit, you will investigate how CAM systems are used in the efficient and effective planning
and manufacture of products. They are used to increase the profitability of manufacturing
organisations by reducing manufacturing costs, improving quality and being more responsive to
customer needs. For example, machining metal is time consuming and expensive, so a ‘right first
time’ approach is a crucial aspect of economic manufacture. You will explore how the manufacturing
process can be automated by moving materials and components efficiently between the machine
tools and workstations that make up a flexible manufacturing system (FMS). You will also simulate
the manufacture of a component from a given specification, using computer-aided design (CAD)
software to draw it and CAM software to simulate the manufacture.
As an engineer, it is important to understand the manufacturing planning systems and process and
how to create products and/or components through the use of CAM systems. This unit will help to
prepare you for a manufacturing engineering apprenticeship and will also help you if you want to
work in a manufacturing technician role. Alternatively, you could choose to study engineering in
higher education.
Learning aims
In this unit you will:
A Examine the benefits, technology and applications of computer-aided
manufacturing systems that improve the operation
B Develop a virtual component on a computer-aided manufacturing system that
simulates its manufacture
C Investigate planning documentation used to optimise the workflow and initiate
manufacture in the operation.
